Abstract
It is shown that light scattering from phonon density fluctuations recently reported by Lyons and Fleury should have a critical depolarized component in systems such as SrTi${\mathrm{O}}_{3}$ near the 105\ifmmode^\circ\else\textdegree\fi{}K transition. Its size is calculated on the basis of available neutron-scattering, specific-heat, and birefringence data. It is concluded that with an appropriate experimental arrangement this component could become observable.
